Network interface device feedback for adaptive and failover multipath routing

摘要: One approach to end-to-end multipath communication establishes multiple flows between two communication endpoints that leverage hop-by-hop and/or flow-based load-balancing (or other schemes) to ensure the flows use different and potentially non-overlapping paths of one or more links through the network to the destination.a sender device sends data through a first flow, while the second flow is kept active in case a link on the path of the first flow fails or is overloaded.
